An 80-year-old woman with acute posterolateralmyocardial infarction, cardiogenic shock, and acute heart failure was admitted to our hospital. Transthoracic echocardiography (TTE) showed dysfunction of the left ventricular inferolateral wall motion and severe mitral valve regurgitation (MR). Emergency coronary angiography revealed triple-vessel stenosis. We performed transesophageal echocardiography in the catheter room to diagnose the cause of MR. Severe tenting of the mitral valve and no rupture of the papillary muscles were revealed. We considered ischemic MR likely to improve with revascularization and performed percutaneous coronary intervention. Subsequently, the patient's circulatory dynamics rapidly stabilized, and MR was significantly improved on follow-up TTE.

Clinical outcomes after percutaneous coronary intervention (PCI) for severely calcified lesions remain poor. The purpose of this study was to investigate the neointimal response after everolimus-eluting stents (EES) for severely calcified lesions treated with rotational atherectomy (RA) using optical coherence tomography (OCT).We retrospectively analyzed 34 lesions in which PCI was performed with EES deployment following RA and OCT was performed immediately after PCI and at follow-up (nine months). The EES was either durable-polymer (DP) EES (22 lesions) or bioabsorbable polymer (BP) -EES (12 lesions). Strut coverage and malapposition were evaluated at 1-mm intervals of cross-section (CS) by serial OCT analysis. Malapposed strut was defined as having the distance from luminal border > 100 μm.A total of 11,823 struts immediately after PCI and 11,720 struts at follow-up were analyzed. Immediately after PCI, the strut-level analysis showed no significant differences in the percentage of malapposed struts between the DP-EES group and the BP-EES group. At follow-up, the BP-EES group showed a more prevalent covered strut compared with the DP-EES group (strut-level analysis: 95% versus 97%, P = 0.045; CS-level analysis: 97% versus 100%, P < 0.01; lesion-level analysis: 27% versus 83%, P < 0.01, respectively).In severely calcified lesions requiring RA, the BP-EES group achieved better neointimal coverage than the DP-EES group at nine months. Additional prospective studies are needed.
